The D-Link DAP-2553 is a wireless N dualband gigabit access point w/ [[wp>​Power over Ethernet|PoE]].

<color red>​**Currently,​ the DAP-2553 is NOT supported. The hardware is, quite likely, qualified for Openwrt, but the DAP2553 seems to have it's own special firmware "​header",​ and at the moment, there is no header calculation tool for the DAP2553. There is a lot of information though, that could help building such a utility, see the [[https://​forum.openwrt.org/​viewtopic.php?​id=52048|dedicated topic on Openwrt forum]]**</​color>​

Source code for this board is available from d-link. Their GPL-site seems to be http://​tsd.dlink.com.tw/​downloads2008list.asp?​OS=GPL,​ at firmware available from https://​dlink-gpl.s3.amazonaws.com/​GPL1400207/​DAP2553_GPL130.tar.gz (v1.30) and https://​dlink-gpl.s3.amazonaws.com/​GPL1300038/​DAP-2553_A1_GPL_1.26.tar.gz (v1.26).

You can now access the "​emergency web server"​ at 192.168.0.50. Uploading the default D-link firmware works. Download ftp://​ftp.dlink.eu/​Products/​dap/​dap-2553/​driver_software/​DAP-2553_fw_revALL_1-30-rc055_all_en_20131108.zip and unpack, and send the "​.bin"​ file to your dap-2553 to unbrick it. It tells us:
